The Yo-kai Detective Agency was formed by Bruno some time after the Oniou Rasen incident, when he asks Summer and Cole if they want to help solve more Yo-kai related incidents. More members join up, including Tate (Summer's brother), Isabelle, and in Yo-kai Watch 4, Nate, Katie and Jack after they end up involved in the events of the game.
